Sea breeze occurs during the daytime. This is because during the daytime, land gets heated up faster than the sea and the warm air above the land rises up. Thus the cold air from the sea flows towards the land causing sea breeze.
Land breeze occurs during the night time. This is because during the night time, land gets cooled faster than the sea and the warm air above the sea rises up. Thus the cold air from the land flows towards the sea causing land breeze.
